This is a step towards making migration unit-testable. This step reduces the need for global state (in the MigrationItem class as class fields) and with another step we can remove the global state entirely and enable unit tests to create migration items without having to worry about other unit tests.

The AgePolicy will let packages stay in the source suite for a pre-defined

amount of days before letting migrate (based on their urgency, if any).
|
|
|
|
The AgePolicy's decision is influenced by the following:
|
|
|
|
State files:
|
|
* ${STATE_DIR}/age-policy-urgencies: File containing urgencies for source
|
|
packages. Note that urgencies are "sticky" and the most "urgent" urgency
|
|
will be used (i.e. the one with lowest age-requirements).
|
|
- This file needs to be updated externally, if the policy should take
|
|
urgencies into consideration. If empty (or not updated), the policy
|
|
will simply use the default urgency (see the "Config" section below)
|
|
- In Debian, these values are taken from the .changes file, but that is
|
|
not a requirement for Britney.
|
|
* ${STATE_DIR}/age-policy-dates: File containing the age of all source
|
|
packages.
|
|
- The policy will automatically update this file.
|
|
Config:
|
|
* DEFAULT_URGENCY: Name of the urgency used for packages without an urgency
|
|
(or for unknown urgencies). Will also be used to set the "minimum"
|
|
aging requirements for packages not in the target suite.
|
|
* MINDAYS_<URGENCY>: The age-requirements in days for packages with the
|
|
given urgency.
|
|
- Commonly used urgencies are: low, medium, high, emergency, critical
|
|
Hints:
|
|
* urgent <source>/<version>: Disregard the age requirements for a given
|
|
source/version.
|
|
* age-days X <source>/<version>: Set the age requirements for a given
|
|
source/version to X days. Note that X can exceed the highest
